A control panel 11, a cabinet door 12 and heat dissipation holes 13 are arranged on the front surface of the box body 10. A refrigeration module, a heating module, a humidification module 43 and a data cable wiring board 21 are arranged inside the box body 10. A number of first interfaces of the data cable wiring board 21 are located outside the box body 10, and each of the first interfaces is electrically connected to the monitoring module. A number of second interfaces of the data cable wiring board 21 are located inside the box body 10, and each of the second interfaces is used to connect a data cable. The monitoring module includes a power supply 31, an oscilloscope 32 and a current and resistance detector 33. After the head and tail ends of the data cable are inserted into the data cable wiring board 21, the data cable conducts a high temperature and high humidity test in a charged state. The data cable wiring board 21 is provided with at least 10 pairs of interfaces for the data cable to conduct a control experiment.

[0019] As an improvement to the above solution, the data cable wiring board 21 is fixed to the side wall of the box body 10 by bolts. A sealing gasket 22 is provided between the data cable wiring board 21 and the side wall of the box body 10.

The evaporator 41 and the condenser 42 are connected in series and, together with a compressor and a throttle valve, form a Carnot cycle. Both the output ends of the evaporator 41 and the condenser 42 are provided with two pipes and corresponding electric valves. One pipe of the evaporator 41 communicates with the heat dissipation hole 13 of the box body 10, and the other communicates with the internal space of the box body 10.
